Each verse is an "American sentence" a 17-syllable form invented by Allen Ginsberg as a Western type of haiku. For this poem I wanted something slightly discontinuous like a ghazal, but with fewer constraints, and the American sentence seemed to lend itself to that end. I had thought of using couplets as in the ghazal, but each sentence fell naturally into three lines — which of course is more haiku-like.
Over at dVerse at present, Gay Reiser Cannon invites us to invent and name our own forms. This is a derivative form, but since it gives me something I've been seeking for years — something looser than a ghazal, which still creates that connection/separation between stanzas with an overall theme — and as I plan to use it again, I'll claim it and name it Ghazal-type 17-3. This may sound a bit clumsy, but allows for me to find more "Ghazal types" in the future.
